It is roughly rectangular that ball circulating member 94a, 94b form the cross section, corresponding with mounting groove 100a, 100b, and have the ball-recirculation hole (second circulation canal) 102 through self inside, and ball 60 is capable of circulation in this passage.On the relative two end part of ball circulating member 94a, 94b, be respectively arranged with rolling counter-portion (roll-reversing sections) 104a, 104b, be used to reverse the loop direction of ball 60. Rolling counter-portion 104a, 104b form has semi-circular cross-section, and the ball grooves that ball 60 therefrom rolls is formed on the outer surface of rolling counter-portion 104a, 104b.Such ball grooves and ball-recirculation hole 102 form uninterrupted connection.Particularly, ball 60 rolls out in the ball-recirculation hole 102 from ball circulating member 94a, 94b, turns to 180 ° to enter first and second bal guides (first circulation canal) 62,74 that are positioned at ball circulating member 94a, the 94b outside by rolling counter-portion 104a, 104b.
In addition, when ball circulating member 94a, 94b are inserted among mounting groove 100a, the 100b of guiding block 92, the planar surface portion 108 of rolling counter-portion 104a, 104b props up the end face (see figure 6) of guiding block 92 respectively, thereby makes ball- recirculation hole 102 and 74 interconnection of second bal guide of ball circulating member 94a, 94b.
Particularly, as shown in Figure 7, in guide mechanism 16, ball-recirculation hole 102 is connected with the orientation that tilts by rolling counter-portion 104a, 104b with first, second bal guide 62,74.
Therefore, continuous ringwise ball-recirculation passage 110 is formed by first bal guide 62 of the ball-recirculation hole 102 of ball circulating member 94a, 94b, described ball grooves, slide unit 14 and second bal guide of guiding block 92.A plurality of balls 60 roll along ball-recirculation passage 110, thereby slide unit 14 can carry out back and forth level and smooth moving along guide mechanism 16.
On the other hand, lid 96 inside is formed with space 114, and rolling counter-portion 104a, 104b are contained in wherein, and the maintenance groove 116 that is used for remaining on the ball 60 that rolling counter-portion 104a, 104b roll also is formed in the space 114.The radial outside that keeps groove 116 to form at rolling counter-portion 104a, 104b has the cross section of arch, makes ball 60 to roll between the ball grooves that keeps groove 116 and rolling counter-portion 104a, 104b.
In addition, when slide unit 14 moved back and forth, the dogbolt 82 of stop mechanism 18 passed the end face that hole 118,111 props up guiding block 92.
The aforesaid structure of linear actuating device 10 basic employings according to the specific embodiment of the invention.Next the operation and the effect of linear actuating device 10 will be described.The end plate 54 of slide unit 14 will be described to initial position against the state of cylinder body 12 end faces among Fig. 4.
At first, the pressure fluid from not shown pressure fluid supply source is injected in first mouthful 26.In the case, second mouthful 28 is in the state that is communicated with atmosphere under the operation of unshowned switching valve in the drawings.
The pressure fluid that is conducted to first mouthful 26 is conducted to through hole 30a, also is conducted to another one through hole 30b by connecting passage 50 simultaneously, thereby makes piston 37 (along the arrow A direction) be pressed towards rod bearing 46.As a result, slide unit 14 is shifted along the direction away from cylinder body 12 with the piston rod 38 that links to each other with piston 37.
At this moment, be accompanied by the displacement of slide unit 14, the ball 60 of guide mechanism 16 rolls along ball-recirculation passage 110, guides vertically thereby make slide unit 14 be guided mechanism 16.
Then, as shown in figure 10, the end that is arranged at the dogbolt 82 of slide unit 14 1 ends props up the end face of the guiding block 92 of guide mechanism 16, and the displacement of slide unit 14 is stopped, and slide unit 14 takes this to arrive at the terminal position of displacement.
After unscrewing locking nut 84 and making that dogbolt can move, stop mechanism 18 can be regulated by screwing dogbolt 82 from the overhang of seat part 64 end faces, thereby the displacement amount of slide unit 14 also can be conditioned.
On the other hand, slide unit along with above-mentioned side in the opposite direction (promptly along direction) away from the position of displacement end shown in Figure 10 the displacement situation under, be conducted to first mouthful 26 pressure flow embodies and to be conducted to second mouthful 28, the first mouthfuls 26 and then to be in the state that is communicated with atmosphere before.The result, by the pressure fluid that infeeds in a pair of through hole 30a, the 30b from second mouthful 28, piston 37 is along direction (direction of the arrow B) displacement away from rod bearing 46, so slide unit 14 is by leveling off to the direction superior displacement of cylinder body 12 by piston 37 with piston rod 38.Then, be arranged on vibration damper 78 on slide unit 14 end plates 54 against the end face of cylinder body 12, so linear actuating device 10 is returned to initial position.
In this manner, the foregoing description provides a kind of like this structure: a pair of mounting groove 100a, 100b under shed is formed on the lower surface of the guiding block 92 of guide structure 16, and therefrom ball circulating member 94a, the 94b in circuit ball-recirculation hole 102 install respectively, are assemblied among mounting groove 100a, the 100b to have ball 60.
Therefore, there is no need to carry out cutting, thereby the number of cost of production and production stage is minimized in guiding block 92, forming ball-recirculation hole 102.In addition, because of generally directly in guiding block 92 required space, this type of ball-recirculation hole of manufacturing 102 no longer essential, so the thickness size of guiding block 92 can reduce (being that guiding block can have thinner profile).As a result, the size of guiding block 92 can be done forr a short time.
In addition, in guide mechanism 16, ball 60 therefrom circuit ball-recirculation passage 110 is formed by ball-recirculation hole 102, rolling counter-portion 104a, 104b, second bal guide 74 of guiding block 92 and first bal guide 62 of slide unit 14 of ball circulating member 94a, 94b.Wherein, ball-recirculation hole 102 is configured to respect to first and second bal guides, 62,74 in the vertical direction biased downward.
And second bal guide 74 of guiding block 92 is positioned at the peripheral side of the workpiece retaining hole 72 of setting slide unit 14 thereon.Therefore, even, for example, the bolt that attaches in the workpiece retaining hole 72 is fastened excessively, so that its end guiding block 92 that is pressed into, conflicts, because ball circulating member 94a, 94b are set at guiding block 92 to be positioned at the bottom of cylinder body 12 sides at it, also can be prevented from putting on ball circulating member 94a, 94b from the pressure of bolt.
As a result, the guide mechanism 16 performed guide functions to slide unit 14 that comprise ball 60 by inside are without prejudice.
In addition, because of ball circulating member 94a, 94b are installed in the guiding block 92 so that ball-recirculation hole 102 to be provided as the different member that forms outside guiding block 92, so, compare the problems such as wall thickness of ball-recirculation hole 102 near zones in the unnecessary again consideration guiding block 92 by the situation that processing guiding block 92 is formed directly into latter inside with this type of ball-recirculation hole 102.Therefore, the ball-recirculation hole 102 of ball circulating member 94a, 94b can be arranged on cylinder body 12 1 sides, and needn't increase the thickness of guiding block 92 for forming ball-recirculation hole 102.As a result, the shape of guiding block 92 can be done thinlyyer.
In addition, in slide unit 14, because the thickness size of matrix component 56 can be done roughly the samely with the thickness size of a pair of guide wall 58a, 58b, so slide unit 14 can be done to such an extent that wall is thin and in light weight.Slide unit 14 can be made by mold pressing, so its manufacture cost can be lowered.
In addition, because end plate 54 is the other ends that are fixed on slide unit 14 matrix components 56 by the bolt 66b that inserts from the top, so, to compare with the situation that is fixed on mechanism's part 56 of slide unit 14 from its place ahead, so fixing end plate 54 can make the thickness attenuation of matrix component 56.As a result, the slide unit 14 that comprises matrix component 56 can be done to such an extent that wall is thin, thereby makes the in light weight of slide unit 14.
